SolidKey Decision Factors for Robot Vacuums
Suction power – Measured in Pascals (Pa) or air watts; higher numbers lift embedded dirt and pet hair.
Navigation AI – Laser‑based SLAM, vSLAM or camera‑guided mapping determines how efficiently the unit covers floors and avoids obstacles.
Mopping capability – Water‑tank size, vibration frequency and auto‑dispensing affect hard‑floor shine.
Bin‑empty automation – Self‑empty docks reduce manual emptying from weekly to monthly.
App controls – Scheduling, zone cleaning, map editing and voice‑assistant integration.
Noise level – Decibels (dB) during cleaning; quieter models suit open‑plan homes and night runs.
Battery life – Runtime per charge and recharge time dictate coverage for large homes.
Price – MSRP vs. discount, factoring in long‑term cost of consumables (filters, brushes, mop pads).
